"A future of hope and opportunity requires that all our citizens have affordable and available healthcare. /applause, cheers/ When it comes to healthcare, government has an obligation to care for the elderly, the disabled, and poor children. We will meet those responsibilities. For all other Americans, private health insurance is the best way to meet their needs. /applause/ But many Americans cannot afford a health insurance policy."
"And so tonight, I propose two new initiatives to help more Americans afford their own insurance. First, I propose a standard tax deduction for health insurance that will be like the standard tax deduction for dependents. Families with health insurance will pay no income or payroll taxes on $15,000 of their income. Single Americans with health insurance will pay no income or payroll taxes on $7,500 of their income. With this reform, more than 100 million men, women, and children who are now covered by employer-provided insurance will benefit from lower tax bills."
I must have missed that in the Constitution somewhere...probably falls under the catch-all "..promote the general welfare...". Family and churches are relieved of their obligations at least.
